SPECIFICATION forming part of Letters Patent N 0. 447,334, dated March3, 1891.

Application filed November 28, 1890. Serial No. 372,812- (No model.)

To all whom it may concern.-

Be it known that I, SINAi LETIECQ, of the city and county of WVorcester,and State of Massachusetts, have invented certain new and usefulImprovements in Power-Shipping I necessary to illustrate my invention;Fig. 2

is a central vertical longitudinal section thereof independent of theshipper and main supporting-frame; and Fig. 3 is a modification 1n theconstruction hereinafter more fully described.

l\ly invention relates more particularly to shipping mechanism fordrilling-machines; but I do not limit myself thereto, as it is equallyapplicable to other machines having back-gearing and in which it isdesirable to change the speed from a low to a high speed, or vice versa.k

Said invention consists in certain improvements in the construction andarrangement of the various parts which constitute said shippingmechanism, as will be hereinafter more fully set forth.

In order that others may better understand the nature and purpose of mysaid improvements, I will now proceed to describe the same more indetail.

In the drawings, the parts marked A represent the upper mainsupporting-frame of the-machine, which in practice is provided withsuitable bearings, as usual, for the shaft B to turn in, one of saidbearings 0 being shown in Fig. 1. To said main frame is secured theframe A, which supports the intermediate gears and shipping device, saidframe A also having a bearing A for. the shaft B to turn in. Upon saidshaft B are mounted the cone-pulley D, sleeve E, gear F, and collar G,which are constructed and arranged as follows: The cone-pulley D isfitted to turn loose on shaft B, is provided with an internal collar D,secured to the shaft for holding said pulley from inward longitudinalmotion, and with atoothed hub D adapted to engage with the sleeve E.Said sleeve E is splined to shaft B and fitted to slide longitudinally,being also provided with a toothed end next to the cone-pulley, adaptedto engage with the aforesaid toothed hub on the pulley to form a clutchbetween the two. The gear F is fitted to turn loose on shaft B and toslide longitudinally between the bearing A and collar G. It is alsoprovided with a toothed hub F next to said collar, adapted to engagewith the latter, which in turn is correspondingly toothed and securedrigidly on shaft B. A sleeve II, having a pinion H thereon, is fitted toturn as well as slide longitudinally on the sleeve E, previously alludedto, and is provided with a toothed end H next to the cone-pulley,(similar to said sleeve E,) adapted to engage with the toothed hub D onsaid cone-pulley, said hub D being of sufficient size to engage with thetoothed ends of both the sleeves E and H, as is indicated in Fig. 2 ofthe drawings.

Upon the ends of the short horizontal shaft I, which turns in frame A,are secured the pinion J and gear K. Pinion J engages with the loosegear F on shaft B and gear K with the loose'pinion H'on sleeveI-I, inturn fitted over sleeve E, as previously stated. An intermediategear-connection is thus made between the gear F, which engages with thefixed clutch-collar G on shaft B, and the clutchsleeve II, which engageswith the cone-pulley. The sleeve E and gear F are connected by means ofa horizontal rod L, fitted to slide in frame A, and forks L L, which aresecured to the ends thereof and fit in annular grooves a a in saidsleeve E and the hub of gear F. A similar slide-rod M on frame A, havinga fork M on one endfengages with the sleeve H, upon which is mounted thepinion H, said fork fitting in an annular groove bin the end of saidsleeve. To the opposite end of rod M from its fork is pivoted theupperend of the shipper N, which is also pivoted to rod L at 95 the leftof its bearing in frame A and to the frame A between said pivots.

By the foregoing construction and arrangement it is obvious that whenthe lower end of the shipper N is moved toward the left the gear F ismoved with it and clutched to the fixed collar G on shaft 13, while thesleeve ll. and its pinion II are moved to the right and clutched to thehub of the cone-pulley D. At the same time sleeve E, being moved to theleft with gear F, is unclutched from said conepulley, therebycommunicating the power from the shaft through the train of intermediategears to the pulley, and at the same time unshipping said pulley fromdirect connection with the shaft, consequently obtaininga low speedthrough said intermediate gearing.

To communicate the speed of shaft B di root to the cone-pulley, and thusobtain the higher rate of speed, the lower end of the shipper is movedtoward the right, said operation causing the gear F to be disconnectedfrom the fixed clutch-collar G, the sleeve II disconnected from thecone-pulley, and the sleeve [E connected with said cone-pulley, as willreadily be seen by reference to Fig. 1 of the drawings.

In said drawings the various parts are shown in the positions that theyoccupy when the cone-pulley is connected direct with the shaft 13through the sleeve E and disconnected from the back-gearing.

In Fig. 3 a similar construction to that hereinbefore described isshown, the clutchcollar G being secured to shaft B and sleeves E and IIfitted to slide and to engage with the hub of the cone-pulley, as in theformer instance, the difference being principally in the arrangement ofsaid sleeves, the sleeve E being in this instance arranged on the shaftwithin the cone-pulley and adapted to engage with the inner end of itshub instead of outside of said cone-pulley and the sleeve II, on whichis mounted the pinion H, being arranged on the shaft instead of over thesleeve E, connection being made between the two sleeves by a horizontalforked rod M fitted to slide in the cone-pulley instead of connectingthe forked rod L with the sleeve E, as in the former instance, and toaccommodate this construction both ends of the cone-pulley hub D aretoothed, as is shown in said Fig. 3. Otherwise the construction andarrangement are substantially the same as in the first two figuresdescribed, and the principle of operation is substantially the same inboth cases, as will readily be seen.

I am aware that other mechanisms of a si milar nature, but differing inconstruction from my invention, have been patented, and I thereforelimit my said invention to the specific construction herein set forth,and pointed out in my claims.
